Field Detail

root

public FileStoreEntry root

myEntry

public FileStoreEntry myEntry

store

public FileStore store

storeName

public String storeName

Constructor Detail

FileStoreEntryFile

protected FileStoreEntryFile(FileStore store)

FileStoreEntryFile

public FileStoreEntryFile(FileStore fs,
                          Handle h)

Method Detail

isValid

public boolean isValid()

exists

public boolean exists()

Specified by:

exists in class FileAdapter

isDirectory

public boolean isDirectory()

Specified by:

isDirectory in class FileAdapter

getLength

public long getLength()

Specified by:

getLength in class FileAdapter

createNew

protected abstract FileStoreEntryFile createNew(FileStore store)

getNew

public File getNew(File parent,
                   String file)

Description copied from class: File

Get a new File object given the directory and new path. This is for objects which inherit from File. The default implementation of this will call getNewInstance() and then call set(File directory,String path). If you do not override getNew() you must override getNewInstance().

Overrides:

getNew in class File

createTree

public static FileStoreEntry createTree(FileStoreEntryFile dest,
                                        FileStore store,
                                        Handle handle)

set

public void set(File parent,
                String file)

Description copied from class: File

Modifies the File to point to a different file on the file system. This means that ewe.io.File objects are not immutable, but this avoids a lot of object creation when dealing with large directories.

Overrides:

set in class FileAdapter

list

public String[] list(String mask,
                     int listAndSortOptions)

Description copied from class: File

Lists the files contained in a directory. The strings returned are the names of the files and directories contained within this directory. This method returns null if the file is not a directory or if the directory can't be read or if the operation fails. If mask is null or "*" then all files will be listed.

The default method calls the list() method and then splits the returned char array.

Specified by:

list in class FileAdapter

Parameters:

mask - A file mask.

listAndSortOptions - Use the LIST_XXX values OR'ed together.

Returns:

An array of file names.

startFind

protected int startFind(String mask)

findNext

protected Object findNext(int search)

endFind

protected void endFind(int search)

getInfo

public Wrapper getInfo(int infoCode,
                       Wrapper sourceParameters,
                       int options)

Overrides:

getInfo in class FileAdapter

getSetModified

protected long getSetModified(long time,
                              boolean doGet)
                       throws IOException

Specified by:

getSetModified in class FileAdapter

Throws:

IOException

move

public boolean move(File newFile)

Specified by:

move in class FileAdapter

createDir

public boolean createDir()

Specified by:

createDir in class FileAdapter

delete

public boolean delete()

Specified by:

delete in class FileAdapter

getFullPath

public String getFullPath()

Specified by:

getFullPath in class FileAdapter

deleteOnExit

public void deleteOnExit()

Specified by:

deleteOnExit in class FileAdapter

toReadableStream

public InputStream toReadableStream()
                             throws IOException

Description copied from class: File

Create and return a Stream to use for reading from the File.

Overrides:

toReadableStream in class File

Returns:

An open Steam that can be used for reading from the File.

Throws:

IOException - if an open stream could not be created.

toRandomStream

public RandomStream toRandomStream(String mode)
                            throws IOException

Description copied from class: FileAdapter

Create and return a RandomAccessStream for reading/writing to the data associated with this File object.

Overrides:

toRandomStream in class FileAdapter

Parameters:

mode - must be "r" or "rw".

Returns:

An open RandomAccessStream

Throws:

IOException - if an open stream could not be created.

toWritableStream

public OutputStream toWritableStream(boolean append)
                              throws IOException

Description copied from class: File

Create and return a Stream to use for writing to the File. If the file does not exist it will be created.

Overrides:

toWritableStream in class File

Parameters:

append - set this true if you want to append to the existing file.

Returns:

An open Steam that can be used for reading from the File.

Throws:

IOException - if an open stream could not be created, or if the file exists but could not be written to or erased (if not appending), or if you requested append but append mode is not supported for this File.
